Snohomish County Design process:
The first step is to have a Septic System Feasibility Study performed on the property to determine if the site perks and if it does what type system the Health District is going to require; This Study costs $ 650.00.
The next step is to have us prepare the full septic system design and submit it to the Health District for their review and approval; The Septic Design will cost $ 2,650.00 (note: we do credit the $ 650.00 from the feasibility study if the full design is ordered within two years of the feasibility study), with an additional Health District Design Review fee of between $ 785.00 - $ 1,000.00 (note the Health District fees are subject to change); If the site is to be served by an onsite Individual Well then the Health District has an additional fee of $ 250.00. It will take us about a week to prepare the Septic Design; The Health District will take between 3-5 weeks to review it; Once approved it will be valid for two years.
Once the Septic System Design is approved by the Health District and you are ready to pursue a Building Permit there is some additional paperwork filing that will need to be done;
Conventional Gravity Flow or Low Pressure Distribution Type System:
No additional paperwork needed, simply apply for the Building permit and have your Certified Installer call us for the Permit Release.
Alternative Type Septic System: ie Sand Filter, Mound, Aerobic Treatment Unit, or Drip Irrigation.
